How to Install a Jandy JEP-R Variable Speed Pump Controller

In this article I go over how to install the Jandy JEP-R Varaible Speed Pump Controller to your Jandy Variable Speed Pump. If you don't have a Jandy AquaLink System then you will need to control your Jandy VS pump with the JEP-R controller.



The JEP-R comes shipped in the open position and the wiring is pretty basic. There is a cable included with your new Jandy VS pump that you can use to connect the pump to the JEP-R. I will go over some details here in this article.

First and foremost, turn off all power to the pump. Also make sure that the PVC plumbing is sufficiently dry before wiring and starting the JEP-R, as the pump may turn on during the programming phase. To learn how to program the JEP-R, refer to this video:

I also suggest before installing the JEP-R controller that you also look into purchasing and using Jandy's new iQPUMP01 interface/controller. The iQPUMP01 is much easier to set-up and program and is far superior to the JEP-R. Here is a quick look at the iQPUMP01:

I know it seems strange to be steering you to an alternate controller but that is how much I like the Jandy iQPUIMP0.

The wiring of the JEP-R is basic. On the back of the JEP-R there is a connection for the four colored wires. They are marked easily for easy installation: Red, Black, Yellow & Green. Just insert the wires and tighten down the screw with a small electronic type screwdriver. After connecting the wires to the JEP-R you are ready to wire it the VS pump.


The VS FloPro in the video and other Jandy VS pumps comes with an area to wire in the JEP-R. There is also a set of Dip Switches that comes factory set for the JEP-R, so you can just leave the Dip Switches in the factory set position. Simple connect the JEP-R for your specific Jandy VS pump – for the VS FloPRo is Red, Black, Yellow, Green. Once you have these wires connected and screwed down, replace the back cover on the pump.


















If you  are using a manual timer box like the Intermatic brand, there is no need to remove the manual timer. Simply remove the on/off tabs and set the timer to the on position. This will effectively bypass the timer and allow you to control the pump from the JEP-R controller.

Once everything is connected turn the power back on and see if the JEP-R lights up. If no errors are present you can now program the JEP-R. It does come factory set with default programs and default set RPM.

Can I Use Clorox Bleach in my Pool?

Image
Regular Unscented Bleach I started doing pool service when I was 16 years old back in 1988. I took a break from the industry and did some Real Estate Investing and ran a small business for awhile. But I always loved working outdoors and so I decided to do pool service again. So I have about 15 years of practical experience in the field. My specialty has always been water chemistry as I was formally trained by an experts in the field. So I am well versed in most of the chemicals that are on the market today and I have used and tested a lot of different products. So when you hear those in the industry discourage and even slander anyone who uses bleach in their pool, you may think that it is not a product that you should use. In fact as you read this article you will find that using bleach and only bleach is a safe and smart choice. There is a lot of ignorance surrounding household bleach and the use of bleach in a swimming pool. Here is a video I made that goes in more detail on usin...

Mr. Pen Non-contact Voltage Meter - Don't Get Electrocuted!

Image
One of the biggest issues you will run into with anything connected to an AC power is if that device or equipment is receiving power. In the pool service industry, this often is the case when you find that a pool pump won’t turn on. Or if a pool timer doesn't on, is it receiving power? Also for repairs with so many breakers being unmarked, how do you know you turned off the right breaker. Bottom line, a non-contact detector like the Mr. Pen is an easy way to see if power is going to the equipment/device and the line is active. A non-contact voltage detector is just that. You don’t need to make contact with the line like with a Multimeter. Plus you don’t need to adjust any settings or knobs to get a voltage reading. Simply hold the Mr. Pen over a cord or wire whip and if there is AC power a red light will turn on and an audible beep will come out of the device. A very easy way to tell if power or a current is present.  To order: https://www.amazon.com/dp/B092LFYTG5?&_encoding=UT...
